Use a large wok or a big roasting pan and line it with foil
Place the tea, rice and sugar on top of the foil
Place another piece of foil on top to cover the rice and tea mix.
Heat this up on top of the stove and it will start to smoke quite quickly.
Place the fish on top of the foil, drizzle with a little olive oil and seasoning
Cover the roasting tin with a secure lid or another piece of foil, making sure that it is secure.
Leave it on moderate heat over the heat for about 15-20 mins.
Turn off heat and leave to cool.
Flake the fish when ready to serve.
